The spectrum of applications for hot-work steel is broad, and the tools manufactured with it are using them in a variety of fields.

Hot Work Tool Steels grade H13 steel is used for the non-cutting forming of workpieces made of iron and non-ferrous metals as well as alloy derivatives at high temperatures.

They are applied in processes such as pressure die casting, extrusion, and drop forging, as well as in tube and glass product manufacturing.

During processing, hot-work tool steel is generally exposed to high temperatures exceeding 200 °C.

The microstructure of this steel should be sufficiently stable and resistant to tempering because microstructural changes must be prevented at all costs.

Tools made from hot-working steel are not only subject to consistently high temperatures when employed, but also to fluctuating thermal stresses occurring where the tool surfaces come into contact with the materials to be processed.

Combined with the wear caused by abrasion or impact, these thermal stresses constitute very specific requirements of the hot-work tool steels.

The key demands are high tempering resistance, thermal shock resistance, high-temperature strength,high-temperature toughness, and wear resistance.

These properties, however, are impossible to realize in only one type of steel at the same time and in the same manner.

The requirements often vary significantly from one tool to the next and are therefore impossible to fulfill with steels from a very limited alloy range.

Steel grades thus have to be selected based on the primary demands of the tool to be employed.

Using high-quality hot-work tool steel is imperative in order to ensure a high degree of operating efficiency and productivity during manufacturing.
